Interaction of tricarbonyl(π-cyclopentadienyl)molybdenum halides and acetylenes
Abstract
Tricarbonyl(π-cyclopentadienyl)molybdenum halides, [(cp)Mo(CO)3X](X = Cl, Br, or I), (cp =η5-C5H6) react with MeCCMe and CF3CCF3 to give the 16-electron bisalkyne complexes [(cp)Mo(RC2R)2X] whilst PhCCPh gives [(cp)Mo(CO)(PhC2Ph)X] and the cyclobutadiene complexes [(cp)Mo(CO)(PhC2Ph)2X].
